what is purely symmetry breaking vs actually fundamental and new

#question
parents:: what does new mean

In understanding this question of "what is new," one needs to make a distinction between what's purely symmetry breaking vs what is actually something fundamentally new.

For example, driving on the right side of the road, that's just a symmetry that had to be broken.
On the other hand, newton's laws of motion were not just a "symmetry in our understanding" that had to be broken: it was something really fundamental.

So, what's the difference?

• [?] what about language?
  • Vocabulary is perhaps just symmetry breaking, while grammar is the truly fundamental part?
  • As evidenced by the huge variety of languages with really no shared vocab. But definitely some common grammar/structure.
